FIELD OF THE INVENTION

The present application is generally directed to systems and methods for tracking and scoring user interactions with content. In particular, the present application is directed to identifying which phrases are trending across an aggregate of users that are relevant to a specific user

BACKGROUND

With the proliferation of mobile devices and mobile applications connected to the Internet and with the growth of social networking and content on the Internet in general, more and more people are sharing content with other people on a regular basis. To share content that people may like or that they think others may like, people may forward links to the content to other people via email, tweeting, texting or posting to a web-site or social networking site. Likewise, those people may in turn forward the forwarded content to other people, and so on. As a result of one person sharing content, a multitude of users may interact with the same content. This sharing and forwarding may occur with a plurality of different content from different sources. It is challenging to identify, track and analyze the forwarding and sharing of such content via the multitude of users, devices and sources of content.

SUMMARY OF THE INVENTION

The servers 106 within each machine farm 38 can be heterogeneous—one or more of the servers 106 or machines 106 can operate according to one type of operating system platform (e.g., WINDOWS NT, manufactured by Microsoft Corp. of Redmond, Wash.), while one or more of the other servers 106 can operate on according to another type of operating system platform (e.g., Unix or Linux).

In one embodiment, servers 106 in the machine farm 38 may be stored in high-density rack systems, along with associated storage systems, and located in an enterprise data center. In this embodiment, consolidating the servers 106 in this way may improve system manageability, data security, the physical security of the system, and system performance by locating servers 106 and high performance storage systems on localized high performance networks. Centralizing the servers 106 and storage systems and coupling them with advanced system management tools allows more efficient use of server resources.

The servers 106 of each machine farm 38 do not need to be physically proximate to another server 106 in the same machine farm 38. Thus, the group of servers 106 logically grouped as a machine farm 38 may be interconnected using a wide-area network (WAN) connection or a metropolitan-area network (MAN) connection. For example, a machine farm 38 may include servers 106 physically located in different continents or different regions of a continent, country, state, city, campus, or room. Data transmission speeds between servers 106 in the machine farm 38 can be increased if the servers 106 are connected using a local-area network (LAN) connection or some form of direct connection. Additionally, a heterogeneous machine farm 38 may include one or more servers 106 operating according to a type of operating system, while one or more other servers 106 execute one or more types of hypervisors rather than operating systems. In these embodiments, hypervisors may be used to emulate virtual hardware, partition physical hardware, virtualize physical hardware, and execute virtual machines that provide access to computing environments. Hypervisors may include those manufactured by VMWare, Inc., of Palo Alto, Calif.; the Xen hypervisor, an open source product whose development is overseen by Citrix Systems, Inc.; the VirtualServer or virtual PC hypervisors provided by Microsoft or others.

Management of the machine farm 38 may be de-centralized. For example, one or more servers 106 may comprise components, subsystems and modules to support one or more management services for the machine farm 38. In one of these embodiments, one or more servers 106 provide functionality for management of dynamic data, including techniques for handling failover, data replication, and increasing the robustness of the machine farm 38. Each server 106 may communicate with a persistent store and, in some embodiments, with a dynamic store.

In some embodiments, the link decoder applies a reverse transformation function to the encoded URL. In some embodiments, the link decoder replaces a portion of the encoded URL with a portion of the URL. In some embodiments, the link decoder un-obfuscates information in the encoded URL to a portion of the original URL. In some embodiments, the link decoder replaces a domain name of the encoded URL with a domain name of the URL.

In some embodiments, the linking system, such as via link decoder, generates, issues or communicates a redirect responsive to receipt of an encoded URL and/or decoding the encoded URL. In some embodiments, the linking system issues any type of 3XX (HTTP redirect. In HTTP, a redirect is a response with a status code beginning with a 3XX that induces a browser to go to another location. In some embodiments, the response or status code includes an annotation describing the reason, which allows for the correct subsequent action (such as changing links in the case of code 301, a permanent change of address). In some embodiments, the linking system issues a 301 type of HTTP redirect. In some embodiments, the redirect response comprises or uses a technique for making a webpage available under many URLs. In some embodiments, the linking system uses scripting for redirection. In some embodiments, the linking system uses a refresh meta tag or HTTP refresh header technique for redirection.

In some embodiments, when the user clicks on or activates the shortened link 211 the user or browser is taken to an interstitial page of the linking system, and then using an HTTP redirect page, an intermediate website of the linking system refers the user to the final destination site of URL 204. While doing so, the intermediate website may track from which website the user clicked on the short link, stores various user specific data, and notes any related cookies, or if there are no cookies, stores a new cookie on the user for the future.

C. Systems and Methods for Scoring Digital Resources

Referring now to FIGS. 3A and 3B, systems and methods for scoring a digital resource, such as content is depicted. These systems and methods score content, URLs, domains, phrases or any entity (all of which are examples of digital resources) based on an expected relevance to an individual user which may be based on that user's previous engagement with digital resources. Relevance is from the perspective of a user to a digital resource. By tracking what digital resources a user has interacted with and analyzing and classifying those digital resources, these systems and methods generate a score that identifies how similar a presented or identified digital resource is to other digital resources the user has engaged with For example, by tracking what content a user has clicked on, and by analyzing and classifying that content, the systems and methods of the present solution, when shown a new set of content, may generate a score determining how similar that content is to other content the user has engaged with. The relevance score produced by these systems and methods provide an indicator of relevance of identified digital resource is to a particular user.

Embodiments of the system of the present solution may take as input: (i) a list of actions associated with a given user (user actions) and (ii) a list of actions associated with entities (global actions). For user actions, the system may identify users via a cookie or a set of cookies. For example, a typical user may have actions associated with a set of cookies, all associated with an individual user. In some embodiments, a cookie-classifier can be used to associate multiple cookies with a specific individual. A list of actions associated with users may be obtained outside of cookies, such as importing web logs or user activity databases. Global actions may include sharing a link, or sharing a piece of content. Typical examples may include a user forwarding a link via email to another user (e.g., the link is the entity, the forwarding is the action). In another example, a global action may include sharing a paragraph of content on a social media platform like a Facebook update (e.g., the update content is the entity, and “shared on Facebook” is the action). Embodiments of the system of the present solution may use click stream 250′ data.

In example operation, the system processes the global actions through a content extractor, which extracts meta-data, phrases, keywords that are specific to the entity. The system may provide the global actions and extracted content as input to a pattern classifier. The system may also provide user actions to the pattern classifier. The pattern classifier may classify the global actions, the user actions and the extracted content into a plurality of classes that is stored by the system. The system may receive a request to score a digital resource for a specific user. For example the digital resource may include piece of data, a keyword, phrase, URL, or domain name, and the user may be identified by a user ID such as the user's cookie ID. The system matches the digital resource and user identifier with the classified data from the classifier, and the output is a content or relevance score and a data score. The relevance score indentifies how closely the digital resource (e.g., new piece of data) matches the digital resources associated with that user. The data score estimates or identified how valid the relevance score is. The data score may be based on how much data was associated with the intersection of the user action and the global actions.

In some embodiments, an ad server serving advertisement or matching content to impression opportunities may transmit the request and/or digital resource identifier and a user identifier to the linking system or relevance scorer. In some embodiments, a client application may transmit the request and/or digital resource identifier and a user identifier to the linking system or relevance scorer.

D. Systems and Methods for Providing Search Results Based on User Interaction with Content

In some embodiments, the present disclosure is directed to systems and methods for providing relevant real-time or static search results. These real-time or static search results may be provided based on user activity and/or engagement measurement from users with respect to particular content and websites. In some embodiments, the linking system 120 may provide or support interactive search based on global engagement patterns of users, for example, across large internet platforms or across multiple platforms. The search results may rank available content based on popularity of the content, which may be determined by user visits and/or referring websites. These results may be determined based on actual interactions between people and content. Such methods, when incorporated into searches, may yield significant improvements over those using typical link crawling and ranking based on links that reside on a page.

Referring to FIG. 4A, one embodiment of a system for providing search results based on user interaction with content is depicted. In brief overview, the system includes a linking system 120 that incorporates a relevance system 405 for facilitating a search request. The relevance system 405 may receive a click stream 250′, as well as keywords or search terms 447 from a search request. In some embodiments, the relevance system 405 includes one or more of the following modules: distribution scorer 410, engagement scorer 415, frequency normalizer 420, source weighting module 425, user weighting module 430, time decay function 435 and search relevance scorer 440. The relevance system 405 may determine a relevancy score for each document identified in a clickstream, for ranking documents during a search.

In certain embodiments, the linking system 120, via a click tracker, may collect, track or otherwise monitor information about links or content accessed by one or more users. The linking system 120 or the click tracker may determine the content that users selected via encoded links, and may analyze the selected content to facilitate interactive search. By way of illustration, and in one embodiment, the linking system 120 may prioritize content and/or links based on one or more of: (i) the identity or other information of the user clicking on the link, (ii) the identity or other information of the website providing the content or link to the content, and (iii) the timing and/or number of users accessing the content via a certain link. In certain embodiments, this prioritization may be determined or computed based on one or more mathematical and/or computer techniques, which may be custom or proprietary to the linking system 120. The linking system 120 may establish, maintain and/or update a database of content or links based on the above determination, analysis and/or prioritization.

The database 230 may include any information or data associated with a click on an encoded link. The database 230 may include data collected, tracked, and analyzed either statically or in real-time, and associated with the click. The linking system, via the click tracker, may analyze and/or parse a clickstream for data to extract and store in the database 230. In some embodiments, the database 230 may store data collected, tracked, and analyzed by the linking system 120 in response to a mouse-over, copy or paste of an encoded link. The linking system may store any portion of the collected data in a record of the database. In some embodiments, a stored record may correspond to a click or other user action. The record may include any user and/or traffic data provided by a web browser, such as those described above in connection with FIGS. 2, 3A and 3B.

In some embodiments, a search engine or system is supported by the linking system 120 in real time or substantially in real time. The search system may change or update the relevancy of content for a user as that user and/or other users click on or navigate links (e.g., encoded links) on a page. The relevancy of a content may be determined in relation to keywords or search terms, user activity and/or activity from various websites. The search system may communicate with or rely on the linking system 120 to process the clickstreams in real time or substantially real time. In some embodiments, the linking system includes a clickstream processing module, which may be referred to as a relevance system 405 or omniflector. The linking system 120 may process or decode a clickstream in real time, and may dissect, organize, buffer and/or store the processed information to the database 230.

In some embodiments, the database 230 may be referred to as a redistribution database or a sharded redis cluster database. The database 230 may comprise one or more sharded redis cluster databases, e.g., in a storage area network (SAN). In certain embodiments, the relevance system 405 may receive and/or process a portion of the clickstream to obtain a social score for each content or document (hereafter sometimes generally referred to as “document” or “content”). The relevance system 405 may perform calculations on a portion of the decoded stream, to generate the social score and/or other data. The linking system 120 may store the social score and/or other data to the database 230. In some embodiments, the linking system, e.g., via the relevance system 405, may receive or access a portion of the stored or buffered information. The linking system 120 may use this information to generate, create, calculate or otherwise determine a social score for each document.

In some embodiments, a social score indicates, describes or represents how popular or in demand a certain document is. In some embodiments, a social score is a weight to be applied to the relevancy scoring. A social score may be determined based on the number of times a document is “clicked” or accessed, and/or how widely the document is being shared or referred (e.g., a corresponding encoded link is forwarded or copied). The social score may be tempered by, or incorporate, a decay function to allow old content to decay, and new content to gain traction, prominence or relevance in searches. The linking system 120 or relevance system 405 may include a decode processor, which may comprise or execute any application, algorithm, program, library, process, service, script, task or any type and form of instructions for determining social scores. In some embodiments, the decode processor includes a chip or a chipset, e.g., a CPU, an application specific integrated circuit (ASIC), a Field-programmable gate array_(FPGA), or any other hardware for determining the social score.

By way of illustration, and not intended to be limiting in any way, the social score may be any real number or integer ranging between 1 and 100 (or any other range). A maximum of 80 points for example, may be mapped, derived, or contributed from a raw social score. A maximum of 10 points, for example, may be mapped, derived, or contributed from a count of the total number of social referrers. A maximum of 10 points, for example, may be mapped, derived, or contributed from a count of the total number of other referrers. The raw score may indicate the reach of a website or a document online, and may include a number of components, including a distribution score, an engagement score, etc. The raw score may have any value larger than one (or zero, in some embodiments). A raw score falling within certain predefined range may be mapped to a value that makes up a portion (e.g., 80%) of the social score. The total number of social and/or other referrers may similarly yield component value(s) that contribute to the final value of the social score. By way of example, one embodiment of a pseudo code or algorithmic description of the determination of a social score is depicted below:

a = raw social score [e.g., weighted number of clicks, weight may indicate the reach of a site on the internet] b = total count of social referrers c = total count of other (e.g., non-social) referrers d = mapped social score [a: 1-400 −> buckets 1-70; a: 401-2000 −> buckets 71-80, > 2000 = 80] e = mapped social referrers [b * 3, may be bounded between 0 and 10] f = mapped other referrers [c / 2, may be bounded between 0 and 10].

In some embodiments, the raw social score may contribute the largest component of the social score. However, various different attribution weights may be implemented in various embodiments, and applied to each of the social score components. In one embodiment, the linking system 120 (e.g., via a source weighting module 425) may assign a weight (e.g., ranging between 1 and 10) to certain websites (e.g., top sites) or documents in accordance with the reach they have on the web. Sites with high or broad reach, such as Facebook and Twitter, may be assigned a weight of 10 or some large value. Lower reaching sites, such as Xing.com, may be assigned a 1 or some small value. In some embodiments, when a social click is identified or detected, the raw social score for a corresponding document is adjusted according to the appropriate, assigned weight. By way of example, a click from Facebook may be worth 10 times as much as a click from Xing, and correspondingly represented by their assigned weights.

The raw social score of a document may continue to increase in value as the document's link receives more clicks. In one illustrative embodiment, the raw score may be mapped to a number between 1 and 80, e.g., with the bottom 70 points mapped to lower raw score ranges, and the last 10 points mapped to higher raw score ranges. In some embodiments, the source weighting module 425 may receive source weight training data 427 to generate an initial social score, or to test the social scoring system. The source weight training data 427 may include weights to assign to certain sites, and these weights may be adjusted or updated as sites are ranked and re-ranked. In some embodiments, the source weight training data 427 may include clickstreams (e.g., simulated, historical, or received in real time) for evaluating source weighting and social scores.

In some embodiments, the relevance system 405 identifies users that triggered the clickstreams and includes a user weighting module 430 configured to weight the social score based on the identified users. The user weighting module 430 may assign specific weights to particular users, such as those identified as influencers (e.g., showing significant social networking reach in sharing content, etc) and/or power users (e.g., performing significant number of searches, which may influence search relevancy in a positive or negative way for other users). By way of example, the user weighting module 430 may measure the value of particular users (e.g., a leading social networker on shoe fashion trends) on specific keywords, search terms or search strings (e.g., “lace up boots”, “tasseled leather pumps”), and may categorize such users as influencers. The user weighting module 430 may weight search results based on identifier influencers, for example boosting search results for content that is either encoded or decoded by influencers. In certain embodiments, the user weighting module 430 assigns weights to clicks associated with certain user data or characteristics (e.g., gender, age group, or users whose online history include visits to websites catering to specific subject matter).

In certain embodiments, the total number or count of social referrers represents the total number of unique referring domains for a certain document or content. These referring domains may be social websites or online social networks. The total number of other referrers may represent the total number of unique referring domains that are not social sites, for a certain document or content. In the above example, the total number of social referrers may be multiplied by three, and the result bounded between 0 and 10. The linking system 120 may divide the total number of other referrers by 2 (or some other number), and bound the result between 0 and 10. Either of these referrer counts may be adjusted by some other predetermined multiplication (or division) factor before contributing to the social score. In addition, either of these referrer counts may be capped or bounded by other ranges (e.g., 0-100) after adjustment.

Any of the above information may be used to determine the social score and/or to determine which documents get indexed within search lists. Once a document is indexed, the relevancy score for a document is determined by a relevance system of the linking system 120 using a combination of word relevancy and the document's social score. The social score may indicate that a document is relatively more important, or is more relevant to a search if the document has been accessed by users and/or from domains (e.g., via encoded links) that have a lot of influence or reach on the web. It may be expected that documents accessed from popular sites may be more popular and relevant to a user in a search. The linking system 120 may index each document identified in a clickstream. The linking system 120 may index or store the document in the database 230 with or against a corresponding social score. This social score of a document may be updated in real time, according to a schedule, or in response to a triggering event (e.g., a search). In certain embodiments, the relevance system 405 and/or search system may access, compare and/or use the social score of a document during a search.

In some embodiments, the social score of a document is determined based on social clicks that access the document via encoded links. In other embodiments, the social score may incorporate one or more types of clicks, which may include non-social clicks. In some embodiments, social clicks include clicks on document links from identified top websites. In some of these embodiments, social clicks include clicks on links from top social sites. The linking system may identify, maintain or track a number of top sites, e.g., 1000 top sites, which may be provided by partners, market research providers (e.g., Doubleclick), analytics (e.g. BlueKai and Exelate) or search providers (e.g., Yahoo, Google and Bing). In some embodiments, the top sites may comprise, exclusively or non-exclusively, major social sites (e.g., Facebook, Twitter, Google+, LinkedIn, etc). The linking system 120 may determine that a click referred, redirected or consummated from one of these top sites or domains may be considered a social click. As an illustration of the relative importance or relevance of social clicks, consider the following: a linking system that focuses on social clicks from the top 1000 sites may be able to index less than 1% of the domains being clicked, but such clicks may account for over 38% of all online clicks. Thus, social clicks may be useful for determining social scores for online content. In certain embodiments, the linking system 120 may dynamically monitor click counts from domains and determine top sites based on the distribution of click counts. The linking system may dynamically identify top sites, e.g., in lieu of a static list of top sites provided by a third party.

In certain embodiments, the linking system may classify or group two or more clicks on a social site for the same document, occurring within a certain time period (e.g., 2 or 5 minutes), as a social click. In some embodiments, the linking system may group multiple clicks from other types of websites as a single social click. Documents identified by a social click may be included in a directory, database, search list, index or application programming interface to index the document for search. In some embodiments, such documents are placed in a publisher/subscriber (pubsub) index or stream that can be pulled during searches. A search engine may pull the social clicks pubsub stream and may continuously index global hashes within the pubsub. Documents that are popular may tend to be clicked over and over again. Such documents may get indexed again and again corresponding to the clicks. As documents' links are clicked, the linking system 120 may update the documents' social scores. As the documents get re-indexed, their corresponding social scores may be higher, resulting in higher rankings within search results.

In certain embodiments, the number of social clicks may contribute to a social score in a linear or non-linear fashion. For example, a social score of a document may be configured such that it is directly proportional to the number of social clicks detected. In some other embodiments, the first clicks (click number 1-80) from a social website may be weighted more than later clicks (click number 81 to 100) in determining a social score. In one embodiment, and by way of illustration, the number of social clicks may be represented as follows:

${sc}_{i,j} = {{\sum\limits_{1,80}\; \frac{s(i)}{10}} + {\sum\limits_{81,100}\; \frac{s(i)}{100}}}$

In some embodiments, s(i) may represent the click count for term i within the respective click count ranges for document j. Additional clicks (e.g., beyond 100) may be weighted less or differently, or disregarded after a certain threshold (e.g., 100 clicks). In certain embodiments, the number of social clicks, sc_(i,j), may be referred to as an engagement score. An engagement scorer 415 of the linking system may rank, score or rate content based on how many clicks are received. An engagement scorer 415 may include or execute any application, program, library, process, service, script, task or any type and form of executable instructions for generating and/or updating an engagement score. The engagement scorer 415 may apply the above function, or some other nonlinear function, such that initial clicks are weighted more than later clicks. The engagement scorer 415 may emphasize initial clicks so that new content may promoted over older content with the same frequency of clicks. The linking system 120 may, for example, promote new content by leveraging on a time decay function in conjunction with the engagement score. The linking system 120 may include or incorporate the engagement score in a social score.

As described, the linking system 120 may calculate the social score for each document, and may stored the social score in an index. The social score may be decayed, reduced or de-emphasized in time for use in searches, e.g., from the time the document is first indexed. A social score may decay down to half of its original score over a configured period of time, such as 72 or 168 hours. In some embodiments, a social score may be decayed as a function of e^(x) (e.g., f(e^(x))), where x represents time. The linking system 120 and/or search system may use the social score to determine a relevancy score. The linking system 120 may include a search relevance scorer 440 for determining and/or updating the relevancy score of a document. The search relevance scorer 440 may include and/or execute any application, program, library, process, service, script, task or any type and form of executable instructions for generating and updating the relevancy score of a document. The search relevance scorer 440 may communicate or interoperate with one or more modules (e.g., distribution scorer 410, engagement scorer 415, frequency normalizer 420, time decay function 435) in determining and/or updating a relevancy score. A relevancy score may sometimes be referred to as a search score or a relevance score. The social score may be one of several factors that determines the relevancy score of a document as pertains to search (e.g., interactive search).

In some embodiments, a relevancy score is based on one or more of weights, factors or components, for example: (i) Social score (e.g., how popular a document is), (ii) time decay (e.g., how long a document has been in the index), and (iii) normalized frequency (e.g., how relevant certain terms are to the text of a document). Other weights, factors or components may include (iv) a distribution score and (v) an engagement score. In certain embodiments, the social score for a document may incorporate one or more of the above components, e.g., time decay, distribution score and/or engagement score. For example, the social score may be subject to time decay prior to being used by the linking system 120 to determine a relevancy score. In other embodiments, the social score may be combined with other factors before being subject to time decay to establish the relevancy score. As discussed, time decay may incorporate an ex function with respect to time (x), or any log-linear time decay function. With the time decay function, new documents with links that are more recently clicked may have a higher social and/or relevancy score.

A distribution scorer of the relevance system may calculate or determine the distribution score or weight for a document. The distribution scorer 410 may include any application, program, library, process, service, script, task or any type and form of executable instructions for monitoring or tracking clicks arising from various websites. The distribution scorer 410 may determine that a document is ranked higher or more relevant in a search if clicks to access such a document arise from a broader set of source web sites. The distribution scorer 410 may determine the distribution of clicks (e.g., counts of social clicks or normal clicks) for the same document across a plurality of sites. In some embodiments, the distribution scorer 410 may determine the number of source sites (e.g., specific social sites) that referred clicks for a certain document. In certain embodiments, the distribution score may be referred as “social distribution”. The distribution score may be calculated, expressed or represented in one embodiment by the following formula:

${sd}_{ij} = {{\max\left( {{\sum\limits_{k}\; n},{Max\_ SD}} \right)}\mspace{14mu} {where}\mspace{14mu} {\sum\limits_{k}\; n}}$

can represent the number of source sites that have been referring clicks for a document. In some embodiments,

$\sum\limits_{k}\; n$

represents the summation of website counts, e.g., over k categories of clicks or k types of websites. Max_SD may be an upper bound or cap for the distribution score (e.g., 100 websites). In some embodiments, Max_SD is optional, and may be set to 0. Where Max_SD is specified, the distribution score may take the larger of Max_SD or the number of source sites referring clicks for the document.

In some embodiments, the linking system 120 includes a frequency normalizer 420. A frequency normalizer 420 may include any application, program, library, process, service, script, task or any type and form of executable instructions for processing a term or word's frequency of occurrence in a document. Once enough traffic has been monitored for clickstream activity, the linking system 120 may retrieve a document identified in the clickstream, using the corresponding long URL. The linking system may extract content that is appropriate for text-based, keyword search. The frequency normalizer 420 may extract key words from the extracted content, and may normalize some of these keywords. In some embodiments, the frequency normalizer 420 may insert or store the keywords and their normalization values into the database 230.

In some embodiments, the frequency normalizer 420 uses a term frequency—inverse document frequency (tf/idf) ratio or metric to obtain the normalization values. This metric may be used as a statistical measure to evaluate the importance of a term or word within a document. The importance of a term may increase proportionally to the number of times the term appears in the document. The importance of the term may be offset by the frequency of the word within a superset of documents (e.g., corpus) comprising the document. The linking system may use the tf/idf metric to score or rank a document's relevance in a given search query. The linking system may use the tf/idf metric to normalize or diminish the weight of terms (e.g., “the”, “of”) that occur very frequently in the corpus and increase or normalize the weight of terms (e.g., “hibernation”, “omnibus”) that occur rarely.

In some embodiments, the tf/idf metric comprises a term frequency (tf) and the inverse document frequency (idf) components. The tf component may represent the occurrence count of a term in a document. The tf component may be determined from the number of times a given term appears in that document, normalized to prevent a bias towards longer documents to give a measure of the importance of the term i within the particular document j. For example, in a document containing 100 words wherein the word brown appears 3 times, the tf value for brown may be determined as (3/100)=0.03. In some embodiments, the tf value is expressed in logarithmic form, e.g., log(0.03). One embodiment of the tf value is presented as follows:

${{tf}_{i,j} = \frac{n_{i,j}}{\sum\limits_{k}\; n_{k,j}}},$

where k may represent the number of distinct terms in the document.

In some embodiments, the idf component is a measure of the general importance of a term. It may be obtained by dividing the total number of documents by the number of documents containing the term, and then taking the logarithm of that quotient. One embodiment of the idf may be represented as follows:

${{idf}_{i,j} = {\log \left( \frac{D}{\left\{ {j:{t_{i} \in d_{j}}} \right\} } \right)}},$

where D may represent the corpus or set of all documents, |D| may represent the cardinality of D, or the total number of documents in the corpus. |{j: t_(i) εd₁}| may represent the number of documents where the term t_(i) appears. By way of example, if there are 10 million documents and the term brown appears in one thousand of these, the inverse document frequency may be calculated as log(10,000,000/1,000)=4.

The normalization frequency of a document term may be determined as the ratio of tf to idf, e.g., tf/idf. In one embodiment, this is represented as:

$\left( {{tf}/{idf}} \right)_{i,j} = {{{tf}_{i,j}/{idf}_{i,j}} = \frac{\frac{n_{i,j}}{\sum\limits_{k}\; n_{k,j}}}{\log \frac{D}{\left\{ {j:{t_{i} \in d_{j}}} \right\} }}}$

In some embodiments, the search relevance scorer 440 may use the tf/idf normalization frequency to determine the relevancy score. However, in some other embodiments, the search relevance scorer 440 may use a different document frequency or a variant of the tf/idf normalization frequency. For example and in one embodiment, the search relevance scorer 440 may use a td·idf weight, which may be represented as:

$\left( {{tf}.{idf}} \right)_{i,j} = {{{tf}_{i,j} \times {idf}_{i,j}} = {\frac{n_{i,j}}{\sum\limits_{k}\; n_{k,j}} \times \log \frac{D}{\left\{ {j:{t_{i} \in d_{j}}} \right\} }}}$

In certain embodiments, the frequency normalizer 420 may compute or determine a td−idf value using Lucene scoring methods. A Lucene score, may, for example, be expressed in the following embodiment:

${score} = {{{td} - {{idf}\mspace{14mu} {value}}} = {{coord} \cdot {queryNorm} \cdot {\sum\limits_{i\mspace{14mu} i\; n\mspace{20mu} q}\; \left( {{td} \cdot {idf}^{\mspace{11mu} 2} \cdot {Boost} \cdot {norm}} \right)}}}$

where coord may be a score factor based on how many of the query terms are found in the specified document. A document that contains more of the query's terms may receive a higher score than another document with fewer query terms. queryNorm may be a normalizing factor for making scores between queries comparable. Boost may represent a search time boost of one or more terms in the query as specified in the query text. Boost may be used to access a boost of one or more terms in a multi term query. norm may include one or more boost and length factors, such as boost factors for specific documents, fields in a document, field length, etc.

In various embodiments, the relevancy scorer 440 may apply different variants of Lucene scoring and the td−idf value in determining the relevancy score. In certain embodiments, for example, different fields in a document may carry different weights. The relevancy scorer 440 may configure these weights as custom properties for a search, a document index, the relevancy scorer 440 and/or frequency normalizer 420 for example. In one embodiment, the relevancy scorer 440 may confer weights or boosts to the following content fields: title=5, meta keywords 3, meta description=4, meta site=4, domain=4, url=3, page=1, globalhash=5, h1=7, h2=5, h3=3, h4=2, cities=3. These may be configured by an administrator and/or determined based on search activity. In some embodiments, arbitrary weights may be assigned and updated based on search activity. By way of illustration, the following is a listing of configured document field boosts:

<entry key=“boosts.site”>4.0</entry> <entry key=“boosts.domain”>4.0</entry> <entry key=“boosts.url”>3.0</entry> <entry key=“boosts.globalhash”>5.0</entry> <entry key=“boosts.phrase”>5.0</entry> <entry key=“boosts.title”>5.0</entry> <entry key=“boosts.description”>4.0</entry> <entry key=“boosts.keywords”>3.0</entry> <entry key=“boosts.lang”>2.0</entry> <entry key=“boosts.h1”>7.0</entry> <entry key=“boosts.h2”>5.0</entry> <entry key=“boosts.h3”>3.0</entry> <entry key=“boosts.h4”>2.0</entry> <entry key=“boosts.cities”>3.0</entry>

Certain variants of Lucene scoring may incorporate boosts values for each document field. For example, Lucene scoring may apply a configuration in which text in h1 tags are more important than those in h2 tags and the title field, which may be more important than the domain field, etc. A document or content may be configured for a relative boost. In certain embodiments, a document or content may not be configured for a boost, although it may incorporate a score or weight in the Lucene scoring method based on the length of text, number of terms in the document and other factors, for example.

In some embodiments, the search relevancy scorer 440 determines the relevancy or search score with the following computation: time-decayed social score*tf−idf value. In another embodiment, the search relevancy scorer 440 may determine the relevancy score using the following formula:

Σ(decay time·Πtd−idf·social distribution score social score),

where Π may represent a direct or Cartesian product of td−idf values. Yet other embodiments may incorporate any of the components described, e.g., engagement score, user weighting, source weighting, etc. The relevancy scorer may rank or index documents based on any variant or combination of relevancy scores, and the highest scoring documents may be returned first in a search.

By way of illustration, a retrieval mechanism may be used to query the database, apply the relevancy score (or a combination of scores described above), and provide a set of search results 450 ordered by how relevant they are in the clickstream. The relevance system 405 may receive keywords or search terms 447 from a search and may process these into a search relevance query 445. Search terms may include one or more parameters that identify or define audience or user segments. These one or more parameters may break down, identify or define users into sub-groups, such as by demographics, communication behavior and media use. In some embodiments, a search term may identify a geography scope or limitation, such as limiting the search to users who live in Italy. In some embodiments, a search term may identify a language scope or limitation, such as limiting the search to users who read content in Italian or interacted or clicked on content in Italian. In some embodiments, a search term may identify an influence rating.

The search relevance query 445 may for example, comprise scores for keywords, indexes into specific groups of documents and/or information about the user. The relevance system 405 may apply the search relevance query 445 against the indexed documents, which are ranked by their relevance scores. By matching document relevance against the query 445, the relevance system 405 may return one or more documents in the search results. The system 405 may return search results limited to or based on any of the audience or user segmentation terms. For example, if a geography term of Italy and a language term of English, the system may return search results based on English based content interacted with, encoded or clicked on by users locating in Italy.

Although some components or factors may be generally referred to or described herein as scores or scoring, these components or factors may be considered weights to be applied to the relevancy calculation or algorithm. For example, a social score, a distribution score, an engagement score, a frequency normalization and/or a time decay function may be considered weights or weighting factors for the relevancy system and may be applied to weight the relevancy score or provide a weight to other components or inputs of the relevancy system.

Referring to FIG. 4B, one embodiment of a method for providing search results based on user interaction with content is depicted. In brief overview, the method includes receiving, by a server, identification of a plurality of clicks of encoded uniform resource locator (URL) links (455). The server may identify, for each of the plurality of clicks, data about a user who clicked an encoded URL link and traffic data associated with a device from which the user clicked the encoded URL link (460). The server may store a record for each click of the plurality of clicks, the record comprising data about the user and traffic data associated with each click (465). The server may determine, based on the records, a relevancy score for each content identified from decoding the encoded URL links (470). The server may communicate, responsive to receiving a request to search content based on a keyword, a set of search results based on the keyword and the relevancy score (475).

Referring now to (455), a server may receive an identification of a plurality of clicks of encoded uniform resource locator (URL) links. The server may comprise any embodiment of the linking system 120 described above in connection with FIGS. 2, 3A and 4A. The server may decode each of the encoded URL links, for example, as described above in connection with FIG. 2. The server may decode an encoded URL link in real time. The server may redirect the click to access a document from another URL.

In further details of (460), the server may identify, for each of the plurality of clicks, data about a user who clicked an encoded URL link and traffic data associated with a device from which the user clicked the encoded URL link. In some embodiments, the server may identify data about the user from a cookie communicated via a click by the user on the encoded URL link. The server may identify, for example, traffic data comprising one or more of a browser type, a referring web site, a source internet protocol address, a destination internet protocol address, a time instance of a click, a document accessed.

The server may identify any other data about the user and/or traffic data as described above in connection with FIGS. 2 and 4A. For example, the server may determine if a user is an influencer or meets certain criteria for increased weighting. The server may assign an appropriate weight to this user's social clicks, e.g., in determining a document's social score. In some embodiments, the server may determine, based on traffic data, if a number of clicks are social clicks that may contribute to a social score, or if a click is triggered from a website identified as a top site and/or a social website. The server may assign a greater weight to social clicks arising from a top site and/or a social website. In certain embodiments, the server may track the number of corresponding clicks from a document, and the distribution of source websites that triggered the clicks.

Referring now to (465), the server may store a record for each click of the plurality of clicks. The server may store the record in any embodiment of the database 230 described above in connection with FIGS. 2 and 4A.

In some embodiments, a distribution scorer 410 of the server may determine a distribution score for each content based on a number of clicks from different sources via one or more encoded URL links to the content. The distribution scorer 410 may determine that a document has a higher distribution score, or is more relevant to a search if clicks to access such a document arise from a broader set of source web sites. The distribution scorer 410 may determine the distribution of clicks for the same document across a plurality of sites. The distribution scorer 410 may track or evaluate the number of source sites that referred clicks for a certain document.

In certain embodiments, the server may determine, via an engagement scorer 415, an engagement score for each content based on a number of clicks received via one or more encoded URL links to the content. Each of the number of clicks may be weighted based on when the click was received. The engagement scorer 415 may determine the engagement score of a document based on the number of social clicks made to access the document. The engagement scorer 415 may rank content based on how many corresponding clicks are received. In certain embodiments, the engagement scorer 415 applies a nonlinear function to click counts such that initial clicks are weighted more than later clicks.

In some embodiments, the server may determine, via a frequency normalizer 420, a frequency normalization value for each content. The frequency normalizer 420 may extract keywords from the content, normalize the keyword counts and may store the keywords and corresponding normalization values into a database (e.g., database 230). The frequency normalizer 420 may extract content from a document, such as text-based content, suitable for text-based keyword searches. The frequency normalizer 420 may determine each term or word's frequency of occurrence in the extracted content. The frequency normalizer 420 may normalize the counts of these terms or words. In some embodiments, the frequency normalizer 420 may use td−idf normalization, such as Lucene scoring, to perform the keyword normalization. The frequency normalizer 420 may provide a td−idf value for each document, to determine the relevancy score of the document.

In certain embodiments, the server may apply a time decay function to the relevancy score based on the length of time a content has been stored in a record after being identified from decoding the encoded URL links. In some embodiments, the time decay function is incorporated into the calculation or formula for determining the social score or the relevancy score, for example, as described above in connection with FIG. 4A. The time decay function may incorporate a log-linear time function in certain embodiments. The time decay function may enable a document with links that are more recently clicked to have a higher social and/or relevancy score.

The server may determine, via a search relevance scorer, the relevancy score of a document by a combination of two or more of a social score, a distribution score, an engagement score, a frequency normalization value, a time decay function, a source weighting component and a user weighting component. The search relevancy scorer may rank or index documents based on any one or a combination of these scores or values. For example, the search relevancy scorer may use relevancy scores to return the highest scoring documents in a search, e.g., based on the closest matching keywords.

In further details of (475), the server may communicate, responsive to receiving a request to search content based on a keyword, a set of search results based the keyword and the relevancy score. The server may receive one or more keywords or search terms from a user or application based on a search. In some embodiments, the server The server may process the one or more keywords or search terms into a search relevance query 445, which may include a processed set of terms and/or priority applied to each of the processes terms. The search relevance query 445 may comprise scores for keywords, indexes into specific groups of documents and/or information about the user. In some embodiments, the server may receive the search relevance query 445 from a search engine or an application. The server may apply or match one or a combination of keywords or terms against a listing, database or index of documents. The listing, database or index of documents may be ordered, ranked or indexed based on the documents' relevancy scores and/or document terms. The server may return a set of search results or documents based on the relevancy scores and/or closest matching terms of the documents. In some embodiments, the server may order the set of search results based on relevancy score of the documents.

In certain embodiments, the server may match a plurality of documents against one or a combination of keywords or terms without using the relevancy scores. The server may identify a subset of documents that most closely matches the one or a combination of keywords or terms. The server may rank this subset of documents based on the how closely the documents matches the one or a combination of keywords or terms. In some embodiments, the server combines this ranking with the relevancy score of these documents, to order the set of search results. The server may, for example, reorder the set of search results based on the relevancy scores or by applying a weighted preference based on the relevancy scores. Using embodiments of the above processes, the server may generate and/or order search results based on the relevance of the documents, e.g., as determined by user interaction, user feedback, and/or based on the popularity of particular content in connection with social media.

The output may be filtered to be domain or content-site specific. In other embodiments, raw or unfiltered output may be useful to aggregators who may provide recommended content from a wider ser of content resources.

Referring now to FIG. 8A, an embodiment of a system for providing a recommendation list of URLs or links given an input or URL link is depicted. In brief overview, the system may include a user tracker 215, click tracker 220 and recommendation system 805. The system may also include a correlation engine 820 that maintains a click co-occurrence map 825 from click streams 250. The correlation engine may correlate via the click co-occurrence map users that clicked on an encoded URL 805 to other encoded URLS those users clicked on 810. The user tracker 215 may identify those who users clicked on the encoded URL 805 and who also clicked on other encoded URLs. The click tracker may identify the number of clicks on the encoded URL 805 and for each of the other encoded URLs the users clicked. The correlation engine may store the click co-occurrence map into a database 230. The recommendation system 805 may receive a URL 205 as input and output a set of URLs based on the click co-occurrence map 825.

The user tracker may comprise any embodiments of the user tracker 215 previously described herein. For any click stream 250′ received by the system 120, the user tracker may identify the user who encoded the encoded URL and each of the other users who clicked on the encoded URL of the user. The click tracker may comprise any embodiments of the user tracker 215 previously described herein. For any click stream 250′ received by the system 120, the user tracker may identify the number of users who encoded the same URL. For any click stream 250′ received by the system 120, the click tracker may identify the number of users who clicked on the encoded URL of a user. The click tracker may identify for each user the number of encoded URLs that user clicked.

Via the user tracker and/or click tracker, the system identifies and tracks the users that clicked on an encoded URL 805. For each user tracked or managed by the system, the system may identify the other encoded URLs 810 that the same users who clicked the encoded URL 805 also clicked. The encoded URL 805 and the other encoded URLs 810 may be encoded URLs of any user. The encoded URL 805 and the other encoded URLs 810 may be encoded URLs of the system. The encoded URL 805 and the other encoded URLs 810 may identify or be associated with any content from any source. For each encoded URL 805, 810 tracked or managed by the system, the system may identify each of the users the clicked on each encoded URL. The system may identify each user via one or cookies. The system may identify each user via information sent with requests to decode the encoded URL. The system may identify each user via the user's account information for the system. In some embodiments, the system tracks the user id of the user who clicked on the encoded URL without tracking other user information. In some embodiments, the system may identify the source (e.g., web-site, social networking site, device, etc) from which the user clicked on the encoded URL, the time and/or geography from which the user clicked on the encoded URL. The system, such as via user tracker and click tracker, may store the users and number of clicks for the encoded URLs 805, 810 to the database 230.

The correlation engine 820 may comprise an application, program, library, service, script, process, task or any type and form of executable instructions executing or executable on a device. The correlation engine may comprise logic, function or operations to correlate any URL to a plurality of other URLs. The correlation engine may comprise logic, function or operations to correlate an encoded URL to a plurality of other encoded URLs. The correlation engine may comprise logic, function or operations to correlate the users the clicked on encoded URLs 805 to the encoded URLs 810 that the same users also clicked. The correlation engine may correlate URLs/encoded URLs to other URLs/encoded URLs based on the number of clicks. In some embodiments, the correlation engine may correlate URLs/encoded URLs to other URLs/encoded URL also based on the source of the clicks, the time of the clicks and/or the influence of the users or who performed the clicks.

The correlation engine 820 may be designed and constructed to generate and/or maintain a click co-occurrence map 825, sometimes referred to as a map. The click co-occurrence map may comprise any type and form of data structure, object, file, table(s) and/or arrangement of data stored in a database. The click co-occurrence map may identify or specify the correlation between URLs/encoded URLs to other URLs/encoded URLs. The click co-occurrence map may identify or specify the encoded URLs 810 for which the users who clicked on the encoded URL 805 also clicked. For each encoded URL 810, the click co-occurrence map may identify or track the number of such users who clicked both the encoded URL 805 and each encoded URL 810. For each of the other encoded URLs, the correlation engine may correlate the users and numbers of clicks on these encoded URLS and further encoded URLs those same users also clicked. In some embodiments, the correlation engine may maintain a click co-occurrence map for a plurality of depths or levels.

In some embodiments, a click co-occurrence map comprises a table, or any programmatic representation thereof, that identifies along one axis, such as the vertical axis, a list of the content the tracked users interacted with and along another axis, such as horizontal axis, each user. The table may identify or indicate for each user in the horizontal axis which content in the list of content in the vertical axis that the user has interacted with (e.g. clicked on). From such a table, the system can identify users who have interacted with the same content (e.g., similar interests). The system can also identify for users with similar interests what content one user may have interacted with or have interest in that the other user has not yet seen or interacted with. By the system performing comparison of similarities and differences between users in the map, the system may make recommendations of content for a particular user.

For each encoded URL 810, the click co-occurrence map may use any number of thresholds to determine whether or not the other encoded URLs has been clicked enough times or by enough users to be put or maintained within the map. For each encoded URL 810, the click co-occurrence map may use any temporal thresholds to determine whether or not the other encoded URLs 810 are put or maintained within the map. For each encoded URL 810, the click co-occurrence map may use any user influence or user weighting to determine whether or not the other encoded URLs 810 are put or maintained within the map. For each encoded URL 810, the click co-occurrence map may use any content relevancy score to determine whether or not the other encoded URLs 810 are put or maintained within the map. For each encoded URL 810, the click co-occurrence map may use any trending score to determine whether or not the other encoded URLs 810 are put or maintained within the map.

The correlation engine may generate and/or maintain a plurality of click co-occurrence maps. The correlation engine may generate and/or maintain a click co-occurrence map corresponding to each encoded URL 805. The correlation engine may generate and/or maintain a click co-occurrence map for a set of encoded URLs 805. The index to a click co-occurrence map may be an URL or encoded URL. The correlation engine may generate and/or maintain a single click co-occurrence map for all the encoded URLs.

The recommendation system 805 may comprise an application, program, library, service, script, process, task or any type and form of executable instructions executing or executable on a device. The recommendation engine may comprise logic, function or operations to provide a recommendation of one of more other URLs given a URL as input. The recommendation engine may comprise logic, function or operations to analyze the click co-occurrence map to determine similarities and/or difference between users in what content users have interacted with or co-clicked and what content users may not have not co-clicked. The recommendation system 805 may comprise any embodiments of the relevance system 405 described herein. The recommendation system may be designed and constructed to receive a URL 205 as input and to produce a set of one or more URLS 820 as output, such as based on the click co-occurrence map.

For any output URL, the recommendation system may provide a score, such as a recommendation or matching score, based on the level of matching via the co-occurrence map. The score may indicate or identify the number of click co-occurrences for the URL in the click co-occurrence map. The recommendation score may indicate the number of other users with similar click history or behavior who also clicked on the recommended output URL. In some embodiments, the recommendation score may be an order or ranking of the URL in the list of recommended URLs. In some embodiments, the score may be a relevance score if a user is specified with the URL input.

The recommendation system may comprise any type and form of interface to receive a URL 205, such as a graphical user, command line interface or programmatic interface. In some embodiments, the programmatic interface of the relevance system 405 may comprise an API, web-service or request/response mechanism. In some embodiments, the recommendation system may receive a plurality of URLs in a single request. In some embodiments, the recommendation system may receive an encoded URL and decodes the encoded URL.

The recommendation system, such as a responsive to receipt of a URL 205, may be designed and constructed to read, process or query a click co-occurrence map for or corresponding to the URL. The recommendation system may obtain or retrieve via the database a corresponding click co-occurrence map, such as by using the input URL as an index for retrieval. Via the click co-occurrence map, the recommendation system may identify or query the URLs that are mapped to the input URL. The recommendation system may output the set of mapped URLs 830 via any the interface, such as displaying via a graphical user interface, output via a command line interface or via a response of a programmatic interface. The recommendation system may rank the mapped URLs by the number of clicks on the mapped URLs. The recommendation system may output an enumeration of URLs 830 by ranking.

The recommendation system may filter any of the ranked or unranked URLs 830 based on a number of clicks threshold. The recommendation system may filter any of the ranked or unranked URLs 830 based on domain filtering. The recommendation system may filter any of the ranked or unranked URLs 830 using content based or content specific filtering. In some embodiments, if a user is also specified with the URL input, the recommendation system may also provide a relevance score for each of the URLs 830 by using any of the relevance scoring systems, methods and techniques previously described herein.

Referring now to FIG. 8B, an embodiment of a method for providing a recommendation list of URLs or links given an input or URL link is depicted. In brief overview, at step 855, the system, such as any embodiments of linking system 120, identifies the users who clicked on an encoded URL. At step 860, the system identifies the plurality of other encoded URLs those users clicked on. At step 865, the system generates a click co-occurrence map, such as to correlate the encoded URL of step 855 to the plurality of other encoded URLs clicked by each user at step 860 who also clicked the encoded URL. At step 870, the system received a URL as input and at step 875, as output, the system provides an enumeration of recommended URLs based on a click co-occurrence map. In some embodiments, the output may also include a ranking and/or recommendation score.

At step 855, the system identifies each of the users who clicked on an encoded URL 805, requested to decode an encoded URL 805 or otherwise interacted with the encoded URL or corresponding URL. For each click stream and/or decoding of the encoded URL, the system may track for each encoded URL the users who clicked on the encoded URL. The system may identify each user via a user id 345. In some embodiments, the system indentifies the user via an account or login of the linking system 120. In some embodiments, the system identifies the user via a cookie 255. The system such as via the link encoder and user tracker may track each instance of the user decoding an encoded link and store that information to the database 230 and/or to the user's profile 710. The system may track when the user decoded the link, what encoded link was decoded and identification of the link and store this information to the database, such as in the user's user profile.

At step 860, for each of the users identified as clicking on the encoded URL 805, the system identifies the other encoded URLs 810 those users also clicked or have clicked. The system via user tracker and click tracker may store in the database a history of encoded URLs each of the users have previously clicked on. The system may also continue to track, such as in real-time, the encoded URLs each of the users are clicking on. For each click stream and/or decoding of an encoded URL, the system may track by user the encoded URLs that user has clicked on. The system may track and store in the user's user profile any information identifying the encoded URLs/URLs that user has clicked on or otherwise interacted with.

At step 865, the system correlates the user and click tracking information, such as the user and click information obtained via steps 855 and 860 to generate and/or maintain one or more click co-occurrence maps. For each encoded URL 805 and for each of the users that clicked on or interacted with each encoded URL 805, the system may identify the other encoded URLs 810 that user also clicked on or interacted with. For each encoded URL 810, the click co-occurrence map may identify or track the number of such users who clicked both the encoded URL 805 and each encoded URL 810. The system may maintain a click co-occurrence map to correlate each encoded URL/URL 805 to the other encoded URLs/URLs 810. The system may maintain a separate click co-occurrence map for each encoded URL/URL. The system may maintain a click co-occurrence map for all encoded URL/URLs that is indexed by or organized by encoded URL. The system may update the click co-occurrence map upon processing each click stream. The system may update the click co-occurrence map upon decoding each encoded URL.

At step 870, the system receives an input identifying or comprising a URL. The system may receive the input via a request. The system may receive the URL as input via a graphical user interface. The system may receive the URL as input via a command line interface. The system may receive the URL as input via a programmatic interface. For example, the system may receive the URL as input via an API call, such as a web service call. The system may receive the URL as input via an HTTP request. The system may receive the URL as input from any component of the linking system 120. The system may receive the URL as input from any third party system, including applications, servers and systems. The system may receive the URL as input from a web page, script or other executable instructions executing on a web page or web server. The system may receive the URL as input from any type and form of mobile application executing on a mobile device, such as a smart phone.

The system may also receive with the URL input or otherwise associated with a request, any one or more parameters for filtering the output. These parameters may include geography information. These parameters may include language information or identification. These parameters may include identification or specification of domain filters and/or content filters. These parameters may include identification or specification of any thresholds, such as number of recommended URLs. These parameters may include identification or specification of a ranking or ordering of the output. These parameters may include identification or specification of providing or generating a score for the URLs in output, such as using any of the relevance scoring techniques described herein.

At step 875, the system provides as output 830 one or more URLs. The system may provide the output responsive to receipt of the URL 805 as input. The system may use the input URL to retrieve, lookup, query or obtain a click co-occurrence map, such as from database 230, for or corresponding to the input URL. Via the click co-occurrence map, the system may identify a plurality of encoded URLs clicked on by users who also clicked on the input URL. Via the click co-occurrence map, the system may determine a plurality of encoded URLs clicked on by the largest number of users who also clicked on the input URL. The system may provide the output 830 via a graphical user interface or command line interface. The system may provide the output 830 as a response to a request, such as an HTTP response to an HTTP request. The system may provide the output 830 as a response or data structure to an API call. The system may provide the output as an enumerated list of URLs. The system may provide the output as an enumerated list of URLs ranked in order based on number of user interactions/clicked and/or relevance.

The system may apply any filtering, such as domain or content filtering, based on any filtering parameters specified via the input or request. For example, the system may exclude URLs from the output that match or correspond to a domain. In another example, the system may exclude URLs from the output that link to or comprise content corresponding to or having keywords corresponding to specified content. The system may apply any threshold based on any threshold parameters specified via the input or request. For example, the system may provide as output a top 10 ranking of URLs. In another example, the system may provide an output of URLs that had at least a predetermined number of clicks (e.g., 100, 1000, etc). As may be requested via the input or the request or otherwise as a default, the system may determine or provide a score with each URL 830 in the output. The system may give each URL in the output a score based on the level or degree of matching or recommendation from analysis of the click co-occurrence map. If a user is specified with the input URL, the system may give each URL in the output a score based on any of the relevance scoring techniques described herein.
